Affiliate Marketing Secrets

I have been an affiliate with a website call MaxBounty for almost a year now. They have ZIP Offers, Email Submit Offers and Address Submit Offers among many other things. I was looking to start hiring people from Craigslist to hand out flyers with these various offers on them, but wanted to get a legal opinion.
Basically I would print the flyers of the offer they want to hand out (would be their choice) then would send them all the flyers. They then could work when they want and hand out the flyers where ever, when ever. They would be paid on commission so I don’t have to pay hourly and keep up with who is doing what. Each person would have a different URL on their flyer so I could track them.
Here are my concerns and questions:
– Is this a serious offense if they’re handing these flyers out?
– I was thinking of making them sign a written agreement that said their soliciting methods were completely up to them and I would in no way be liable for any damages. Is this necessary? If so, should I write it up, or should I have a lawyer?
– Some of these offers are like this: Test & Keep an Xbox 360 FREE. In the ad it does say details apply, but I have never asked exactly how all that works. Are these legal? Would it be an issue if the person handing the flyers chose one of these to hand out?
– Should each person get a soliciting license for a certain municipality to only hand out in the city? Or is this not necessary?
– If there were issues with the person handing the flyers out, would I ever be held accountable? Given that I’m just the middle man, I wouldn’t think there would ever be issues brought on me, especially considering I’m not making them hand them out in certain area. Also, the offers that the people would be sent to are not programs that are owned by me.
Thanks in advance for any help!
